I have been struggling to write a North African campaign (including the siege of Malta and the invasion of Greece) that fits the ethos on which the PAM timeline has been built. That is : Plausibility within the political and industrial constraints existing at the time. I have so far written three alternative story lines.
1, Very much as OTL, just that the RAF does a little better due to there being slightly better and more aircraft available in the middle east. The political and strategic shambles of OTL remains completely unchanged.
2. Due to there being better air cover and more of it Operation Compass is a little more successful, The Intervention of the Luftwaffe from Scilly and the Italian mainland is blunted by their being more Hurricanes and other aircraft available on Malta. With the early capture of Cyrenaica and the Italian Airfields reinforcements can be flown in from there (As OTL). Intervention by the RAF and the RN prevents the German Africa corps ever successfully forming in Libya
No army units are sent to Greece and the Desert Army advance to capture the whole of Libya by the end of April. Greece and Crete both fall, the RAF take losses in both areas.
3. As above but Crete is Garrisoned by British troops and the Airfield reinforce with more fighters. The Desert Army get west of Sirte and then fight a joining battle with the Africa Corps as it moves forward. The Campaign then see saws for the rest of 1941. Greece is lost but Crete holds. The desert Campaign is won in late 1941 due to there being no ‘Gasala Gallops’ as in OTL due to there being more divisions in the desert to face Rommel. This situation is helped by the RAF developments under the PAM.
I am not sure which scenario is the most likely and plausible but I personally favour version three as it seems consistent with the story line and more compatible with the state of the Army and Navy ITL.
However you might have different ideas and suggestions?
I hope to resume posting soon.
